Exploring heat and energy at the smallest scales

(Phys.org) —In a recent experiment at SLAC’s Stanford Synchrotron Radiation Lightsource (SSRL), scientists “tickled” atoms to explore the flow of heat and energy across materials at ultrasmall scales. The experiment, detailed in the May 6 edition of Structural Dynamics, enabled them to see subtle light-driven changes in the atomic structure of thin materials, relevant to thermoelectric and electronic devices.
